Use same method to detect presence if system is capable of NETCFG_TYPE=scripts as in netcfg-scripts - by checking for presence of -x /etc/sysconfig/network-scripts/ifup, not just directory -d /etc/sysconfig/network-scripts/ which exists, because OS has put placeholder text file, describing that given configuration method is deprecated by OS.

Give full control over the NIC to the user when NIC=[METHOD=skip] is
set. 

NOTE: If you decide to switch back METHOD to something other than skip (like METHOD=auto or METHOD=dhcp) then please reboot the VM.

NOTE II: IPv6 configuration will be also skipped
